Description

液晶显示装置
技术领域
本发明涉及液晶显示技术领域，尤其涉及一种液晶显示装置。
背景技术
液晶显示装置(LiquidCrystalDisplay，LCD)具有机身薄、省电、无辐射等众多优点，得到了广泛的应用。如：液晶电视、移动电话、个人数字助理(PDA)、数字相机、计算机屏幕或笔记本电脑屏幕等，在平板显示领域中占主导地位。
现有市场上的液晶显示器大部分为背光型液晶显示器，其包括液晶面板及背光模组(BacklightModule)。液晶面板的工作原理是在薄膜晶体管阵列基板(ThinFilmTransistorArraySubstrate，TFTArraySubstrate)与彩色滤光片基板(ColorFilter，CF)上施加驱动电压来控制两基板之间液晶分子的旋转方向，以将背光模组的光线折射出来产生画面。
由于液晶显示面板本身不发光，需要借由背光模组提供的光源来正常显示影像，因此背光模组成为液晶显示器的关键组件之一。背光模组依照光源入射位置的不同分成侧入式背光模组与直下式背光模组两种。直下式背光模组是将发光光源例如阴极萤光灯管(ColdCathodeFluorescentLamp，CCFL)或发光二极管(LightEmittingDiode，LED)设置在液晶面板后方，直接形成面光源提供给液晶面板。而侧入式背光模组是将LED灯条(Lightbar)设于液晶面板的侧后方作为背光源。
在现有的中小尺寸液晶显示器件的设计中，其背光模组与液晶显示面板为分离架构，各自的驱动电路的也相互独立，驱动电路上的元器件也为独立的设计。同时，液晶显示装置的组装一般也采用分体组立。例如，在背光模组组立完成后，再进行液晶显示面板及其驱动电路的重合。
请参阅图1，现有液晶显示装置包括：液晶显示面板2’、及设置于液晶显示面板2’底面的背光模组1’；液晶显示面板2’一侧设有与液晶显示面板2’电性连接的第一柔性电路板20’；背光模组1’包括：胶框11’、设置于胶框11’底面的反射片12’、设置于反射片12’顶面胶框11’内侧的导光板13’、设置于导光板13’与胶框11’之间的背光源14’、设置于背光源14’顶面的与背光源14’电性相连的第二柔性电路板15’、及设置于所述导光板13’顶面的扩散片及光学膜片16’。其中，第二柔性电路板15’为背光源电路板，表面设有背光源电路，用于使背光源14’发光；第一柔性电路板20’为液晶显示面板驱动电路板，其上设有包括限高元器件31’(如电容、电阻等)的驱动电路30’，用于对液晶显示面板2’进行驱动。在该液晶显示装置中，第一柔性电路板20’从背光模组1’的顶面开始沿背光模组1’的一侧面反折至背光模组1’的底面，部分带有限高元器件31’的驱动电路30’反折至背光模组1’的底面，使限高元器件31’的位置成为背光模组1’底面的最高处，影响液晶显示装置的厚度，并且易使液晶显示装置内部产生干涉。现有技术针对这一问题主要有两种方案：其一是调整驱动电路30’上的驱动元器件31’的高度，此方法会增加产品成本及影响驱动的可靠性；其二是优化液晶显示装置的堆叠架构，对机构件(如前框与中框)进行破孔或减薄工艺，此方法将会影响整机厚度规格及增加产品成本。

所述液晶显示面板2包括：液晶显示面板本体21、以及设于所述液晶显示面板本体21一侧的与液晶显示面板本体21电性连接的第一柔性电路板20；
所述背光模组1包括：胶框11、设于胶框11内的背光源14、以及设置于背光源14顶面及胶框11表面上的与背光源14及第一柔性电路板20均电性连接的第二柔性电路板15；
所述第二柔性电路板15上设有背光源驱动电路；
所述第一柔性电路板20与第二柔性电路板15上设有液晶显示面板驱动电路，所述液晶显示面板驱动电路包括多个限高元器件22；
所述多个限高元器件22设置于所述第二柔性电路板15靠近所述胶框11的一侧表面上，所述胶框11对应于第二柔性电路板15上设置限高元器件22的位置设有容纳所述限高元器件22的避位孔111。
具体地，所述限高元器件22为安装后高度超过预设的高度上限的元器件，例如电容与电阻等常见的安装后高度较高的元器件。此外，所述液晶显示面板驱动电路还包括多个高度低于所述限高元器件22的非限高元器件21，所述多个非限高元器件21设于所述第一柔性电路板20上。所述限高元器件22与非限高元器件21共同组成液晶显示面板驱动电路。
具体地，所述的液晶显示装置还包括：设置在所述液晶显示面板2顶面的玻璃盖板、设置在所述背光模组1底面的中框、设置在所述中框底面一侧的小主板、设置在所述中框底面的扬声器、及设置在所述玻璃盖板底面包覆所述液晶显示面板、背光模组、驱动电路、前壳与中框、小主板、及扬声器的后壳。
此外，所述背光模组1还包括：设置于所述胶框11底面的反射片12、设置于所述反射片12顶面的导光板13、以及设置在所述导光板11顶面的光学膜片组16。其中，所述背光源14设置于所述导光板13与胶框11之间。所述光学膜片组16包括自下而上依次层叠设置的扩散片、下棱镜片、及上棱镜片。
具体地，所述避位孔111的位置可根据需要进行选择，优选地，所述避位孔111设置于胶框11的顶面、侧面、及底面中的一个或多个位置。
进一步地，所述第一柔性电路板20与第二柔性电路板15电性连接在一起，从而可以将液晶显示面板驱动电路分成两部分并分别分布在第一柔性电路板20与第二柔性电路板15上，且能够正常驱动液晶显示面板。可选地，请参阅图2，在本发明的第一实施例中，所述第一柔性电路板20与第二柔性电路板15为独立的两块柔性电路板，所述第一柔性电路板20与第二柔性电路板15通过连接器23电性连接。可选地，请参阅图3，在本发明的第二实施例中，所述第一柔性电路板20与第二柔性电路板15为一整块柔性电路板上的两个区域。
值得一提的是，上述液晶显示装置通过将液晶显示面板驱动电路中的限高元器件22与背光源驱动电路共同设置在第二柔性电路板15上，液晶显示面板驱动电路21中的非限高元器件设置在第一柔性电路板20上，并且在背光模组1的胶框11上设置避位孔111，使限高元器件22能够位于胶框11中的避位孔111中，当第一柔性电路板20反折到背光模组1底面时，使背光模组1底面的第一柔性电路板20的上最高点的位置降低，相比现有的将限高元器件设置在背光模组1底面的第一柔性电路板20上的技术方案，能够降低第一柔性电路板20的最高点的位置，从而降低液晶显示装置的厚度，提升产品的竞争力。
具体地，所述第一柔性电路板20从所述背光模组1的顶面开始经过背光模组1的侧面反折至背光模组1的底面。而所述第二柔性电路板15可只设置于所述胶框11的顶面及侧面，从而在所述背光模组1的底面仅有第一柔性电路板20，能够进一步降低第一柔性电路板20的最高点的位置和液晶显示装置的厚度。
综上所述，本发明提供的液晶显示装置，包括：液晶显示面板、及设置于所述液晶显示面板底面的背光模组；通过将第一柔性电路板与第二柔性电路板电性连接到一起，并将液晶显示面板驱动电路中的限高元器件与背光源驱动电路一同设置到第二柔性电路板上，同时在背光模组的胶框上设置避位孔来容纳限高元器件，能够有效减少液晶显示装置的厚度，提升产品的竞争力。
以上所述，对于本领域的普通技术人员来说，可以根据本发明的技术方案和技术构思作出其他各种相应的改变和变形，而所有这些改变和变形都应属于本发明后附的权利要求的保护范围。
